Operation CFX75DZW, CFX95DZW
14
Re-fit the centre hinge in the new position.
Insert the lids in the hinges on the opposite side (fig. 6 D, page 4).
Selecting the temperature units
Temperature display units can be switched between Celsius and Fahrenheit as
follows:
Switch on the cooler.
Press the “SET” button (fig. 3 4, page 2) three times.
Use the “UP +” (fig. 3 10, page 2) or “DOWN –” (fig. 3 9, page 2) buttons to
select Celsius or Fahrenheit.
The selected temperature units then appear in both displays for a few seconds.
The displays flash several times before returning to the current temperature.
7.2 Energy saving tips
Choose a well ventilated installation location which is protected against direct
sunlight.
Allow warm food to cool down first before placing it in the cooling device to
keep cool.
Do not open the cooling device more often than necessary.
Do not leave the cooling device open for longer than necessary.
Defrost the cooler once a layer of ice forms.
Avoid unnecessarily low temperatures.
7.3 Connecting the cooler
Connecting to a battery (vehicle or boat)
The cooler can be operated with 12 V
g or 24 Vg.
A
For safety reasons the cooler is equipped with an electronic system to prevent
polarity reversal. This protects the cooler against short-circuiting when connecting to
a battery.
NOTICE! Danger of damage!
Disconnect the cooler and other consumer units from the battery before
you connect the battery to a quick charging device.
Overvoltage can damage the electronics of the device.

CFX75DZW, CFX95DZW Operation
15
Using the fused DC plug
A
Plug the DC connection cable (fig. 1 2, page 2) into the DC voltage socket of
the cooler (fig. 4 5, page 3).
Connect the connection cable to the DC power outlet.
Connecting to AC mains (e.g. in the home or office)
D
The coolers have an integrated multi-voltage power supply with priority circuit for
connecting to an AC voltage source. The priority circuit automatically switches the
cooler to AC operation if the device is connected to an AC power supply, even if the
DC connection cable is still attached.
When switching between the AC power supply and the DC battery supply, the red
LED may light up briefly.
Plug the AC connection cable (fig. 1 3, page 2) into the AC voltage socket of
the cooler (fig. 4 1, page 3).
Connect the connection cable to the AC power outlet.
NOTICE! Danger of damage!
For protection of the device the DC cable supplied includes a fuse inside
the plug. Do not remove the fused DC plug.
Only use the DC cable supplied.
DANGER! Danger of electrocution!
Never handle plugs and switches with wet hands or if you are
standing on a wet surface.
If you are operating your cooler on board a boat with an AC mains
connection, you must install a residual current circuit breaker
between the AC mains and the cooler.
Seek advice from a trained technician.

7.4 Using the battery monitor
The device is equipped with a multi-level battery monitor that protects your vehicle
battery against excessive discharging when the device is connected to the on-board
DC supply.
If the cooler is operated when the vehicle ignition is switched off, the cooler switches
off automatically as soon as the supply voltage falls below a set level. The cooler will
switch back on once the battery has been recharged to the restart voltage level.
A
In “HIGH” mode, the battery monitor responds faster than at the levels “LOW” and
“MED” (see the following table).
The battery monitor mode can be selected as follows:
Switch on the cooler.
Press the “SET” button (fig. 3 4, page 2) four times.
Use the “UP +” (fig. 3 10, page 2) or “DOWN –” (fig. 3 9, page 2) buttons to
select the battery monitor mode.
Digital display will be as follows:
Lo (LOW), Πd (MED), HI (HIGH)
The selected mode then appears in the display for a few seconds. The display
flashes several times before it returns to the current temperature.
I
NOTICE! Danger of damage!
When switched off by the battery monitor, the battery will no longer be
fully charged. Avoid starting repeatedly or operating current consumers
without longer charging phases. Ensure that the battery is recharged.
Battery monitor mode LOW MED HIGH
Switch-off voltage at 12 V

Make sure that the ventilation slots are not covered and that the heated air can
dissipate.
I
Connect the cooler, see chapter “Connecting the cooler” on page 14.
A
Press the “ON/OFF” button (fig. 3 1, page 2) for between one and two
seconds.
The LED “P” lights up (fig. 3 2, page 2).
The displays (fig. 3 6 and 7, page 2) switch on and show the current
temperatures.
Depending on the compartment set temperatures, the cooler starts cooling
either one or both compartments.
The LEDs (fig. 3 5 and 8, page 2) light up when the respective compartment is
cooling.
I
NOTICE! Danger of overheating!
Ensure at all times that there is sufficient ventilation so that the heat that
generated during operation can dissipate. Ensure that the ventilation
slots are not covered. Make sure that the device is sufficiently far away
from walls and other objects so that the air can circulate.
NOTE
Place the cooler as shown (fig. 1, page 2). If you operate the box in a
different orientation it can be damaged.
NOTICE! Danger from excessively low temperature!
Ensure that the only those objects are placed in the cooler that are
intended to be cooled at the selected temperature.
NOTE
When operating with the battery, the display switches off automatically
if the battery voltage is low. The LED “P” flashes orange.

Resetting the Wi-Fi to factory settings
In case you have personalized the Wi-Fi settings of your cooling device using the
Wi-Fi app and forgotten your password, you can reset to the factory settings as
follows:
Press the “SET” button (fig. 3 4, page 2) six times.
Hold the “UP +” (fig. 3 10, page 2) button for at least five seconds.
In both displays “rES” will blink several times before returning to the previous
display.
The Wi-Fi settings have been reset to factory settings.
For additional information visit the Dometic website from which you downloaded
the app.
NOTE
The default setting for the Wi-Fi transmitter is off. For first time use and
whenever power to the device is interrupted, switch on the Wi-Fi
transmitter to use the app.
The Wi-Fi transmitter uses a small amount of power. For optimal
energy performance switch the Wi-Fi transmitter off if it is not being
used.

7.10 Using the emergency switch
The emergency switch (fig. 4 3, page 3) is located below the control panel. For
normal operation the switch is in the “NORMAL USE” position.
If an electronic control failure occurs, slide the switch to “EMERGENCY
OVERRIDE” position.
I
NOTE
The factory setting of brightness of the display is d0 (default).
If a fault occurs, the brightness automatically is d0 (default). After
troubleshooting the set brightness is reactivated.
NOTE
If the switch is in the “EMERGENCY OVERRIDE” position, the cooler
circuit runs with full cooling capacity and, depending on the running
conditions of each compartment at the time of switching, may either
freeze one or both compartments, and/or stop cooling one of the
compartments.

7.11 USB port for power supply
The USB port allows you to charge small devices like mobile phones and
mp3-players.
To use your cooling box with any USB devices, simply connect a USB cable (not
included) to your device.
I
7.12 Switching off the cooler
Empty the cooler.
Switch the cooler off.
Pull out the connection cable.
If you do not want to use the cooler for a longer period of time:
Leave the lids slightly open. This prevents odour build-up.
7.13 Defrosting the cooler
Humidity can form frost in the interior of the cooling device or on the evaporators.
This reduces the cooling capacity. Defrost the device in good time to avoid this.
A
To defrost the cooler, proceed as follows:
Take out the contents of the cooling device.
If necessary, place them in another cooling device to keep them cool.
Switch off the device.
Leave the lids open.
Wipe off the defrosted water.
NOTE
Ensure that any small device connected to the USB port is compatible
with 5 V/500 mA operation.
NOTICE! Danger of damage!
Never use hard or pointed tools to remove ice or to loosen objects
which have frozen in place.
